Allow user to precise the largest profile to use for encoding due to target decoder constraints. For instance, if CABAC entropy coding mode is requested by "constrained-baseline" profile only is desired, then an error is returned during codec configuration. Also make sure that the suitable profile we derived actually matches what the HW can cope with. https://bugzilla.gnome.org/show_bug.cgi?id=719694
